TROUBLE SHOOTING
The following instructions are listed in the order of the most common difficulties encountered
during the installation and start-up.
► The actuator does not respond

Visually inspect the actuator and check if no damage has occurred during shipping and handling of
the actuator.

Verify the line voltage supplied to the actuator; it must match with the rating on the actuator’s
nameplate

Compare and check the internal wiring with the supplied wiring diagram of the actuator

Check the limit switch cams
► The actuator is supplied with power but does not operate

Verify the line voltage supplied to the actuator; it must match with the rating on the actuator’s
nameplate.

Make sure that the actuator output torque is greater than the required valve torque

Check the limit switch cams

Check if the torque switches have not been tripped

Check the mechanical travel stop adjustment

Check if the rotating direction matches (According to the applicable standards, valves and actuators
must open in counter-clockwise direction)

Check the internal wiring

Check for any corrosion and condensation. Electrical or mechanical devices may have been
affected

Verify if coupler/bracket is correctly installed and may not block the actuator rotation
► Actuator runs erratically

Check the ambient temperature

Verify that the duty cycle has not been exceeded

Check the position of the manual override lever
► Optional Equipment(s)
1) Potentiometer

Check the resistance value

Check the potentiometer gear for jamming

Check the ZERO and SPAN calibration and confirm input/output signal

Check the board for any damage
2
) Current Position Transmitter

Verify the input signal

Check the configuration of the dip switches

Check the board for any damage
